It still isnt quite clear to me what you're asking for - can you be more precise?
That is, if you're writing d3 js code, the best way to make that available to others is JS. Each Java-to-JS compiler first assumes that the next developer is using Java, but each makes their own assumptions about how to map JS ideas to Java, so there isn't a one-size-fits-all approach. JsInterop types at least are mostly the same for both J2CL and GWT - but if you have a user who doesn't use GWT, they probably also don't use Java in the client at all?
